DETAILED DESCRIPTION

With reference to the drawings, the disclosure provides a spinal bracesystem 10 of improved construction and configured to provide multipleconfigurations of spinal braces. In particular, the spinal bracesprovided by the spinal brace system 10 are configurable to be used as aLumbar-Sacral Orthosis (LSO) and two different Thoracic-Lumbar-SacralOrthosis (TLSO) configurations, one having a sternal pad (TLSO-S) andthe other having a dorsal lumbar extension (TLSO-D).

The spinal braces according to the disclosure are particularlyconfigured to provide support and immobilization in the sagittal,coronal and/or transverse planes to aid in the relief and recovery frompostoperative fusion, postoperative laminectomy, postoperativediscectomy, compression fractures, degenerative disc disease,osteoporosis, chronic low back pain, spondylolisthesis, spondylolysis,spinal stenosis, spinal osteoarthritis, and facet syndrome.

With initial reference to FIG. 1 , the spinal brace system 10 includescomponents that may be selectively utilized in various combinations toprovide the desired brace configuration most optimal for the patient'sinjury. For example, as shown, the spinal brace system 10 includes asselectable components: trimmable lateral panels 20, an adjustable belt30, an anterior panel 40 having a sternal pad kit (SPK) 50, and aposterior panel 60 having a removable posterior thoracic extension (PTE)70, and a removable dorsal lumbar extension (DLE) 80.

The lateral panels 20, the posterior panel 60 and the posterior thoracicextension 70 are made of injection molded plastic and compressed foam.Thus, in combination with the adjustable belt 30, when a brace accordingto the disclosure is applied about the patient will compress around themidsection of the patient to offer stabilization to the spinal column.

By selective use of the components 20-80, the spinal brace system 10 isconvertible between three different spinal brace configurations. ATLSO-S spinal brace configuration 10 a is shown in FIG. 2 and FIGS.8A-8D. An LSO spinal brace configuration 10 b is shown in FIG. 3 andFIGS. 9D and 10A-10C. A TLSO-D spinal brace configuration 10 c is shownin FIG. 4 and FIGS. 11B and 12A-12B.

As discussed in detail below, FIGS. 9A-9D show conversion from theTLSO-S configuration to the LSO configuration. FIGS. 11A-11B showconversion from the LSO configuration to the TLSO-D configuration.

Returning to FIG. 1 , the trimmable lateral panels 20 have panelsegments 20 a, 20 b, 20 c and 20 d joined by trim guides 22. The trimguides 22 are configured as thin demarcations between the panel segmentsthat are easy to cut and follow during cutting. A hook/loop material 24may be provided on the proximal ends of the panels 20 for releasableattachment of the lateral panels 20 to the posterior panel 60.

As best seen in FIG. 13D, the adjustable belt 30 has cable tensioners32, such as cable reels available under the name BOA from BoaTechnology, Inc. of Denver, Colorado. The cable tensioners 32 facilitatesnug fitting of the belt once the desired length of the belt isachieved.

To adjust the length of the belt 30, an adjustment plate 34 is providedhaving spaced apart belt passage slits through which the belt 30 ispassed and belt engagement members 36 that are pivotally adjustablerelative to the plate to engage or disengage the belt 30. The beltengagement members 36 are engaged with the belt to maintain a desiredlength of the brace, and are disengaged from the belt to permitadjustment of the length of the brace. A soft fabric plate cover 34 a isattached to the back of the plate 34 and the belt 30 as by matinghook/loop material. An exemplary adjustment plate 34 may be provided bythe adjustment plate structure described in U.S. Pat. No. 10,143,582entitled ADJUSTABLE BACK BRACE, assigned to DeRoyal Industries, Inc. andincorporated herein by reference in its entirety.

The belt 30 also has belt ends 38. The ends 38 may be of fixed positionor may be removable and adjustably positionable as by hook/loopmaterials at the ends of the belts 30. By positioning the ends 38 asdesired, the belt 30 may be further custom fit so as to be a desiredlength. Once the desired belt length is selected, a desired tension ofthe belt 30 is achieved by use of the cable tensioners 32. Also, aspanning segment may be utilized to span between the ends 38 if thegirth of the patient is such that the ends 38 cannot be positioned tooverlap. The spanning segment may be removably positionable to the ends38 or the belt 30 as by hook/loop material.

With reference to FIGS. 5A-5D the anterior panel 40 has an integratedadjustable mount 42 for adjustably mounting the sternal pad kit 50 ontothe anterior panel 40. The mount 42 includes wedged levers 44operatively associated with a retaining arm 46 having pins 46 a andlocated within a channel 48. An anterior panel cover 40 a provided by asoft loop material attaches to anterior panel 40 using hook material.The cover 40 a provides a surface that is soft and to which hookmaterial associated with the belt 30 may adjustably attached.

With reference to FIGS. 1 and 8D, the sternal pad kit 50 has a sternalplate 52 having a pad 52 a supported by an adjustment post 54 havingadjustment apertures 54 a. The post 54 is received in the channel 48 ofthe adjustable mount 42 of the anterior panel 40. Shoulder straps 56 maybe attached to the posterior of the brace as explained below.

Returning to FIGS. 5A-5D, to insert and adjust the height of the sternalpad 52, a user will pinch the wedged levers 44 and this motion will movethe retaining arm 46 and pins 46 a out of position. An advantage of thisdesign is that the wedged levers 44 will bottom out or run out oftravel. Thus, the retaining arm 46 can only travel back so far, and willnot enter permanent deformation. When the levers 44 are released the pin46 a will be fully inserted through the apertures 54 a, making failureless likely to occur.

As best seen in FIGS. 1, 6A, 7B and 13A, the posterior panel 60 is arigid panel locatable at the posterior of a wearer of the brace adjacentthe spine of the wearer. The posterior panel 60 includes a centralflattened apex 62 configured for releasably receiving the posteriorthoracic extension 70. The posterior panel 60 includes apertures 60 a,60 b, and 60 c stacked along opposite sides thereof. As describe below,the apertures 60 a-60 c enable anchor points for adjustably anchoringstraps associated with the dorsal lumbar extension 80. Likewise, theshoulder straps 56 of the sternal pad kit 50 may be adjustably anchoredto the apertures 60 a-60 c.

With reference to FIGS. 6A-6C, the posterior thoracic extension 70 has apadded surface 70 a, central clips 72 and lateral oppositely facingelongate clips 74. The central clips 72 and elongate clips 74 cooperatewith the flattened apex 62 for releasable mounting of the posteriorthoracic extension 70 to the posterior panel 60.

The dorsal lumbar extension 80 creates a high degree of thoracic spineimmobilization. With reference to FIGS. 7A-7C, the extension 80 includesan attachment arm 82 that secures to the back of the posterior panel 60as by hook/loop material. The dorsal lumbar extension 80 also includesstraps 84 that may be anchored in any of the apertures 60 a-60 c whichserve as anchor points for the straps 84. The adjustable nature of theseanchor points 60 a-60 c offer the clinician the ability to optimize theamount of motion restriction, and comfort of the brace to end user, andease of donning and doffing the brace. The dorsal lumbar extension 80also includes an internal rigid stay 86, preferably of plastic.

FIGS. 8A-8D show components of the brace system 10 configured to providethe TLSO-S spinal brace configuration 10 a, which includes the sternalpad kit 50, the anterior panel 40, the posterior panel 60, the posteriorthoracic extension 70, and lateral panels 20. The brace configurationmay be adjusted to match the patient's progression through recovery. Forexample, the sternal pad kit 52 may be removed from the TLSO-S spinalbrace configuration 10 a to give the patient a larger range of motion.

FIGS. 9A-9D show conversion from the TLSO-S spinal brace configuration10 a spinal brace to the LSO configuration 10 b. As depicted, theconversion steps include removal of the sternal pad kit 50 and theposterior thoracic extension 70, followed by removal of the lateralpanels 20 and the anterior panel 40.

FIGS. 10A-10C show the LSO spinal brace configuration 10 b. As shown, itincludes only the belt 30 and the posterior panel 60.

FIGS. 11A-11B show conversion from the LSO spinal brace configuration 10b to the TLSO-D spinal brace configuration 10 c. As shown, this involvesinstallation of the dorsal lumbar extension 80 onto the posterior panel60.

FIGS. 12A-12C show the TLSO-D spinal brace configuration 10 c. As shown,it includes only the belt 30, the posterior panel 60, and the dorsallumbar extension 80.

The brace system 10 therefore advantageously enables multipleconfigurations and each of these configurations enables for use as aninventory stock-keeping unit (SKU). For example, it has been discoveredthat the brace system 10 enables the use of only three different SKU'sfor configurations effective to treat over 90 percent of patientconditions. For example, the LSO spinal brace configuration 10 b may beselected for most L5-S1 pathologies, the TLSO-D 10 c spinal braceconfiguration may be selected for most T6-S1 pathologies, and the TLSO-Sspinal brace configuration 10 a may be selected for most T6-S1pathologies.
